机器人穿衣系统能适应手臂移动,通过视觉与力觉反馈提升安全性和成功率。

Force-Modulated Visual Policy for Robot-Assisted Dressing with Arm Motions

  • 基于仿真训练的视觉策略,结合真实世界少量数据微调。
  • 264次真人测试中成功为12人穿好两件长袖衣物,适应多种手臂动作。
  • 适合需辅助穿衣的残障人士,对动态肢体有强适应能力。

机器人辅助穿衣有望显著改善行动障碍者的生活质量。为确保有效且舒适的穿衣体验,机器人必须处理易变形衣物、施加适当力道,并在穿衣过程中适应肢体运动。以往研究常假设人体肢体静止,限制了实际应用。本文提出一种可应对视觉遮挡、并鲁棒适应手臂运动的机器人穿衣系统。基于部分观测下于仿真中训练的策略,我们提出一种方法,在真实世界仅用少量数据和多模态反馈(视觉与力觉)进行微调,进一步提升对臂部运动的适应性与安全性。我们在简化的人体关节模型上进行仿真评估,并在包含12名参与者、共264次试验的真实人类研究中验证该方法。结果表明,该策略成功为参与者穿上两件日常长袖衣物,表现出对各类手臂动作的高度适应性,任务完成率和用户反馈均显著优于现有基线。视频见 https://dressing-motion.github.io/。

原文摘要 · Abstract (English)

Robot-assisted dressing has the potential to significantly improve the lives of individuals with mobility impairments. To ensure an effective and comfortable dressing experience, the robot must be able to handle challenging deformable garments, apply appropriate forces, and adapt to limb movements throughout the dressing process. Prior work often makes simplifying assumptions -- such as static human limbs during dressing -- which limits real-world applicability. In this work, we develop a robot-assisted dressing system capable of handling partial observations with visual occlusions, as well as robustly adapting to arm motions during the dressing process. Given a policy trained in simulation with partial observations, we propose a method to fine-tune it in the real world using a small amount of data and multi-modal feedback from vision and force sensing, to further improve the policy's adaptability to arm motions and enhance safety. We evaluate our method in simulation with simplified articulated human meshes and in a real world human study with 12 participants across 264 dressing trials. Our policy successfully dresses two long-sleeve everyday garments onto the participants while being adaptive to various kinds of arm motions, and greatly outperforms prior baselines in terms of task completion and user feedback.
